SI-IOCK-EQRMING ATTACHMENT FOR- Application filed. Gctober 23,

This invention relates to harvesting maed upon a harvester as an attachment thereto and acting automatically to receive and group together the bundles of grain discharged. by the harvester and to form them into shocks which are subsequently deposited upon the ground, the device having the great advantage of mak ng it unnecessary to employ additional help to gather together the bundles of grain and. form, manually, into shocks, as is the common practice.

An important object is the provision of a device of this character which may be manufactured as a complete and separate entity and attached to an already existing harvestor without making any material changes in the construct on thereof or additionsthereto, it being consequently unnecessary to construct a specially designed harvester for the pi'irpose.

A further object of the invention is to provide shock forming machine of this character including means for supporting the individual bundles of grain received from the harvester until such time that the sufiic number of bundles have been grouped together to form a complete shock, the device -.furtl'ier including an automatictrip mechanism whereby the completed shock will be deposited upon the ground and the varioijss parts be restored to in tial or normal position ready to have another shock form thereon.

lhe object of the invention, more particularly stat d. is to provide a shock forming machine e ibodying a device of a supporting nature adapted to be mounted upon a hari and carrying a rotatably mounted carrier having a series of elements thereon for moi-ting bundles of grain discharged the harvester, the construction and operation being such that upon the completion ot a revolution ot the rotary carrier the supporting element for the grain bundles will be moved to elect depositing of the shock formed by the various bundles upon the ground.

The invention further contemplates the provi ion oi? a device of this character eml a l 1. pr various novel features in the struc genient and the combination otli "hereh to insure rapidity in action.

various improvements manifestly constituting a distinct improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction, and the arrange ment and combination to be hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which Figure l is a plan view of the complete device showing it attached to a portion of a harvester, the hood tor the bundles being removed in this view. a t

Referr ng more particularly to the drawings. the letter A designates a. portion ofa harvester and B represents the kicker shaft therein driven by any suitable means through the instrun'ientalitv of a chain C engaged about u. sprocket D. I

In carrying'out the invention we provide a suitable frame designated broadly by the numeral 1. which frame may be of any desired size. shape and material and COnstructed of any preferred or necessary number oi. parts such details being immaterial to a clear understanding of the invention. The manner of mounting the frame withrespect to the harvester mechanism is likewise a mere detail which could be varied without departing from the spirit of the invention in an spect. Mounted within the shafts 2 and 3 icurnaled within 1e 1 are any suitable bearings and carryingrollers 4- and 5 about which is engaged an endless belt or apron (3 preferably provided with transverse slots or cleats '7 and defining an elevator receiving the bundles of grain, designated by the letter E, cischarged from the harvester itself The shaft 2 carries a sprocket 8 about which is trained a chain 9 in turn trained about sprocket 10 on the shaft B so that when the shaft B is driven by whatever means is provided the elevator apron or conveyor structure 6 will be operated to carry the bundles of grain (lisehar zed from the harvester into a receiver 11 likewise mounted upon the frame and receiv ng from the conveyor 6.

'Ihe numeral 1E2 designates a rod and secured to or formed as a continuation of the member ii and carrying fingers 13. On the rod 1:2 is a sleeve 12 carrying a bevel gear 1% meshing with a bevel gear 15 on a short shaft 16 suitably mounted. The shaft 16 also carries a disk 17 equipped with a wrist pin 18 with which is connected a pitman 19 in turn connected with a crank 20 on one end of a shaft 21 which is formed with a crank portion 22 located beneath and secured to the receiver 11. Obviously, when the sleeve 19. is rotated the shaft 21 will he correspondingly rotated so that the bundles passing from the harvesteronto the eonveyoro and thence into the receiver 11 will be deposited onto the shock forming device itself.

The shock forming device just referred to is of course carried by the frame 1 and includes a stationary upstanding shaft upon the upper end of which is mounted a guard 21 twhich may be of an open frame-like construction and which is preferably shaped to form a portion of a sphere. The frame I carries a stationary support 25 upon which is rotatably mounted a table 26. both of these elements being formed with suitable races in which are engaged bearing balls 27 for the purpose of reducing friction. The table member "36 carries a bearing member 28 at its top from which radiate arms 29 secured thereto and to the table 26 by any preferred or suitable means. At the ends of the arms are angular bracket members 30, adjacent ones of which journally support shafts 31 on which are mounted substantially eliptical shaped pan members for supporting the bundles of grain. In the present instance it will be observed that there are eight of these pan members provided although this is merely for purposes of illustration as a greater or less number may be used if preferred, depending upon the size of the shock to be formed or the s ze of the bundles constituting the same. Journaled along the arms 29 in suitable bearings 33 thereon are radially extending shafts 3a which have their outer ends carrying bevel gears 35 meshing with bevel gears 36 on the shafts 31, it being observed that each shaft 31 is provided at only one end with a bevel gear. Obviously, when the shafts 3% are rotated the engagement of the gears 35 and 36 will effect tilting of the pan lllQlTllJGlS 32 so that the bundles supported thereon will be deposited upon the ground.

The inner ends of the shafts 3i carry spur gears 37 meshing with a circular rack or crown gear 38 which is rotatably mounted upon the upstanding shaft or post 23 and which is urged downwardly into close ongagement with the gears or pinions 37 by means of a suitable coil spring 39 bearing against a stop collar on the shaft or post 23. Journaled on the stationary frame 1 and beneath the table is a shaft 41 upon one end of which is a bevel gear 42 meshing with abevel gear 43 rotatably mounted upon a shaft 4i and carrying a sleeve -15 terminating in clutch element 46. Spliued upon the shaft t l is a second clutch element 4;? carryingor formed upon a grooved collar 48 with which cooperates a shifting lever 49 pivoted at :30 upon a bracket or auxiliary frame structure 51 suitably mounted on the frame 1. At its lower end the shaft ate carries a bevel gear meshing with a bevel gear 53 on the shaft Projecting from one side of the frame or bracket structure 51 is a stub shaft fii: upon which is rotatably mounted a cam 55 having a plurality of high points corresponding in number to one half the number of pan members of the rotatable shock forming device. The cam 55 has a ratchet face 5T with which cooperates a pawl 58 mounted on an arm 5!) rotatable upon the stub shaft 54-. Pivotally connected with the arm 59 a link or rod (10 which is in turn pivotally C(IUII'lBCi'Qtl with a crank arm hi. on the shaft 21. The shaft 41 above de cribed, has its inner end provided with a spur gear (31, u'leshing with a circular rack or crown gear 63 on the uiu'lerside of the table or platfi'um 26. Obviously, when the shaft 12-1 is driven the platform or table 26 carrying all of the pans 32 will be rotated, the rotation being step by step on account of the intermittent driving of the shaft -l-l. ()ne of the shafts 34 is provided with an extension or carrying a spur gear (55 adapted to mesh with a sc, mental rack 66 carried by an u] )standi1ig bracket 67' mounted on the frame 1.

iihile it istrue that the pan members 32 are pivotally suppcu'tcd from the arm so as to be capable of being inverted for the purpose of depositing the formed shock upon the ground. it is necessary to provide means for preventing accidental or unintentional swinging of these pan members. It should also be mentioned in passing, that these pan members have both ends exactly alike so that either end may be the inner or I it) lilo either the outer end, depending upon cir cumstances and the action ct themechanism as will he described. The'meeus for normell" preventing the pan members from rotating with the shafts upon which they are mounted compv hes a plurality of latch fingers 68 pivoted at upon the arms 29 and their outer ends disposed be Heath the inner ends of the pins 32 as clearly indicated in F igure i. The inner ends of the latch fingers 68 are all pivotally connected by neahs of intermediate links it) as clearly ioicated in the same figure, cud one latch linger provided with an inward extension 1 with which is connected a coil spring 72 suitably anchored to the under.- eide ot the turn teole whereby to hold all oi the latch finger in operative position, a stop 73 being provided for limiting the movement of this extension U Garried by the static my support 2 is an upstanding pin 74 disposed in the prth of travel of the extension 71 on the above described latch finger wher by upon engage-i ment with this iupstendihg pin the latch member having the extension, and consequently all the others 4W1 .l he swung so that the outer ends thereof will be removed from obstructing relat on to the pan members 32 so that thclstter may tilt and deposit the shock or bundles of grain upon the ground. The pan meu'ibers 32 are so belaiiced that after this action oocursthey will return to normal position by the simple process of swinging entirely over and by the time they have reached this position the extension 71 will have passed by the pin 7 ft so that the spring 72 will return allot the latchlhigers to their normal positions in obstructing relation to the pans 32 for hold ing the latter temporarily stationary.

In the operation of the device it will be seen that the shafts and 2 are constant ly rotating; but that the shaft lt rotates freely Within the gear 43 except when the clutch members 4.! and e"? are in engagement. The bundles of grain discharged from the harvester of course pass along or are carried upwerdlyby the conveyor 6 to the receiver 11 and every time the gear 1.5 is rotated through a complete revolution, the wrist pin 18 thereon connected by means of the link or pitman 19 with the croul; 20 on the shaft 21 Will operate to turn the letter so that the crank portion 22 thereon mounted beneath and carrying the receiver 11 will. act to swing this receiver upwardly and toward the rotatable shocl; forming de-- vice or carrier. As the shaft 21v is roteted or rocked, the latter being the preferable and more direct term, the crank arm 61 thereon will operate to move the link or red GO and consequently the arm 59 carrying; the pawl 58 sothat the com will be driven step by step by virtue of the pawl and high points 56 thereon will engage the shift:

ing for]: or lever -l9 and swing it upon its pivot to bring the clutch member 4;? JiltO eiwao ement with the clutch member 46.

Vv hen this is done the shaft ie-is locked for rotation by the shaft 2 and the gear on the shaftt l meshing with the gear 42 will act to rotate the shaft 41 cerryiiig the spur gear 62 which meshes with the CFOW'H es on the underside of the rotatable table or platform 26. The parts are so timed that the rotatable platform or shock carrier vvill be given a one-eighth turn andin this Way it is obvious that-the successive pan members 82 are brought into proper position to receive the successivebundles of gram ted thereonto by the tilting action Oil the receiver 11. has made a complete revolution the spur gear 65011 the extension shetttllwill come into engagement with the segmental reek 66 and at the same time theeigtension 71 on one latch finger will come into engagement with the upstanding pin it that all of the latch fingers will be swung; into nonobstructing; relation to the inner ends of the pan members 32. l i hen the spur gear 65 has come into engagement w' h the so mental or orcuate rack 66 and the rotetive movement of the shock carrier is continued, it ie obvious that the shaft 6% will be rotated so that the gear 39 will operate to turn the crown gear 38, As the latter mentioned crown gear is in mesh with all of the spur gears 37 it is obvious that ell o the shafts 34 Will then be driven and this will result in rotation of the gears 35 and 36 so that thoshufts Slwill be turned, carrying with them the pans 82 and permittii he completed shock formed by the various bundles, eight in the present instance, to slide downwardly and be deposited upon the ground. O vi to the particular construction and peculiar mounting of the pan members 32 it is obvious that they willcontinue to turn, after the bundles have been deposited and return to normal. position, By this time thevextension 71 on the elougz-zted latch linger has moved. past the stop pin 74: so that the spring 79, will have returned. all of the latch fingers to normal position engaged by the pan members 32 for holding; the latter eta tionery. The operation is then couthu ed in exactly the same manner until the nest shock has been formed and deposited, and the entire acvio is repeated as long; as the mechanism is in operation;

i-rvrom the foregoing; description and a study ot the drawings it is apparent that we have thus provided comparatively simp e de ce or the purp spec fied e d After the shock carrier Hill one which will act practically automatically, no attention being required other than to see that the various parts are in their proper relation. It is believed that the construction, operation and advantages will be readily apparent to one skilled in the art Without further explanation.

While We have shown anddescribed the preferred embodiment of the invention, it is of course to be understood that We reserve the right to make all suchchanges in the form, construction and arrangement of parts as Will not depart from the spirit ofthe invention or the scope of the subjoined claims.
